What is the purpose of a web application firewall in WMSL security?

The purpose of a web application firewall (WAF) in WMSL security is to monitor and filter incoming traffic to protect against attacks. This security tool functions as a barrier between web applications and the internet, analyzing and controlling HTTP traffic. By actively inspecting the data flow, a WAF can detect and block various types of cyber threats, such as SQL injection, cross-site scripting (XSS), and other vulnerabilities that web applications may face.

This protective measure is crucial for ensuring the integrity and safety of the web application, preventing unauthorized access and data breaches. By focusing specifically on the application layer of the network, a WAF plays a vital role in maintaining secure operations within web environments.

The other options do not align with the primary function of a WAF, as enhancing user interface design, managing application programming interfaces, and expediting database queries are not directly related to the security and traffic filtration roles that a WAF is designed to perform.
